Abstract (en)

[origin: EP3992223A1] The invention relates to thermoplastic elastomer compositions comprising an aromatic thermoplastic polyurethane and a block copolymer comprising at least one polymer block substantially consisting of repeating units derived from at least one vinyl aromatic monomer, and at least one polymer block substantially consisting of repeating units derived from isobutylene, derivatives of isobutylene and/or mixtures and/or mixtures thereof. The thermoplastic elastomer composition exhibits improved slip resistance and is advantageously used as material requiring anti-slip properties, preferably as soling material for shoes, in particular safety shoes.
